Write a quadratic equation for a parabola with roots at (-2, 0) & (4,0) and a y-intercept at ( 0, -16) Write your answer in factored form
9514 1404 393
Answer:
y = 2(x +2)(x -4)
Step-by-step explanation:
The y-intercept will be a constant times the product of the roots. Here, the product of the roots is (-2)(4) = -8, so the constant of interest is -16/-8 = 2. That constant is the coefficient of the leading term of the quadratic, so is a multiplier of the factored form.
y = 2(x +2)(x -4)

To control his weight, Joel reduced his calorie intake from 2500 calories to 1950 calories each day. What was his percent decrease for calorie intake?
Answer:
22%
Step-by-step explanation:
The change in calories = 1950 - 2500 = -550
percent decrease for calorie intake = (change in calories / initial calorie intake ) x 100

Answer:40 teenagers
Step-by-step explanation:
To find the answer to this question, you would have to divide 2000(amount of people) by 100 to find the amount of people for 1%. After you find that, you would multiply the answer by 2. Equation: 2000÷100= 20 · 2= 40.

Calculate the slope of the line passing through the points (-1, -5) and (-9, -1)
a) undefined
b) 0
c) -0.5
d) -2
Answer:
C
Step-by-step explanation:
(y2-y1)/(x2-x1) = slope
y2-y1 = (-1)-(-5) = 4
x2-x1 = (-9)-(-1) = -8
slope = 4/(-8) = -0.5

−2 1/4=r−4/5
Help
Plz
Answer:
r=-29/20
Step-by-step explanation:
because
-2 1/4 will be -9/4=r-2/5 now you add 2/5 to both sides
witch means you have to increase the denominator to the greatest common denominator of 4 and 5 witch is 20 multiply the number used to combine with the denominator to get 20 to the numerator so itll be -45/20+16/20 witch will be -29/20 so there fore r=-29/20 or 1 9/20.

Mark wants to make an enclosure for his cows.
He has 44 metres of fencing.
He wants the width to be 8 metres less than the length.
What dimensions should the field have?
?
Answer:
the length and width be 15 meters and 7 meters respectively
Step-by-step explanation:
The computation of the dimension of the field is given below;
Let us assume the fencing be p
Length be x
And, the width be x - 8
So,
P = 44
P = x - 8 + x - 8 + x + x
= 4x - 16
Now
4x - 16 = 44
4x = 44 + 16
4x = 60
x = 15
And, the width be 15 - 8 = 7
So, the length and width be 15 meters and 7 meters respectively

When the equation is written in slope-intercept form of ;
y = mx + b, then m is the slope and b is the y-intercept
In this case;
1. y= -7/6x + 1 --------- m= -7/6 ; b = 1 --------b
2. y=7/6x -1 ------------m = 7/6 ; b = -1 ---------c
3. y= x-7/6 -------------m = 1 ; b = -7/6 ---------d
4. y= -x -7/6 ----------m =-1 ; b = -7/6 ----------a
5. -x + 6/7 ------------m = -1 ; b = 6/7---------e

Two of the desserts are sugar/free. Three of the drinks are sugar-free. A meal deal combination is selected at random. Work out the probability that both the desserts and the drink are sugar free. Give your answer as a fraction
Answer: 8/15
Step-by-step explanation:
You need part a of the question to answer this question correctly. In part a of the question it is said there is 6 sandwiches, 3 desserts and 5 drinks.
Two of the desserts are sugar free (2/3).
Four of the drinks are sugar free (4/5)
Times these fractions together, 2/3x4/5= 8/15.
Hope this helps :)
The probability of selecting a sugar free dessert and drink is 2/5
Number of sandwiches = 6
Number of dessert = 3
Number of drinks = 5
Sugar free drinks = 3
Sugar free dessert = 2
Recall :
Probability = required outcome / Total possible outcomes
P(both dessert and drink are sugar free) :
(sugar free dessert) × p(sugar free drink)
(2 /3) × (3 / 5) = 6/15 = 2 / 5
Hence, the probability of selecting a sugar free dessert and drink is 2/5

Lattice has £15000 in a savings account at the start of the year. How much will she have at the end of the year if the annual interest rate is 7.5%?
Answer:
£13 875
Step-by-step explanation:
first you have to find out how much is 7.5% of 15 000 and you find it by calculating 0,075 times 15 000 which becomes 1 125. then you take out that answer from your first answer which is 15 000 - 1 125= 13 875

18w2(squared) - w - 39
Answer:
w = 1.5 and -1.44
Step-by-step explanation:
Given the quadratic equation 18w^2 - w - 39
Using the general formuls
w = 1 ±√1²-4(18)(-39)/2(18)
w =1 ±√1+2808/36
w =1 ±√2809/36
w = 1+53/36 and 1-53/36
w = 54/36 and -52/36
w = 1.5 and -1.44

Answer:
49π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 14, so r = 14 ÷ 2 = 7, then
A = π × 7² = 49π cm²
Answer:
49pi cm^2
Step-by-step explanation:
[tex]a = \pi \: {r}^{2} [/tex]
Because the radius is half of the diameter, divide it by 2 to get the radius to place in the formula which is 14 ÷2 = 7
so
A = pi × 7^2
A= pi × 49cm^2
